WINDOW.

Specification of Letters Patent.

Application filed April 4, 1913.

Patented Dec. 16, 1913. Serial No. 758,897.

To all whom it may concern Be it known that I, Donsnr'r A. DAVISON, a citizen of the United States, residing at Richmond, in the county of Henrico, State of Virginia, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements in windows.

As is well known the ordinary type of window which usually embraces a pair of vertical sliding sashes, is defective in certain important respects such as in facility for cleaning, protection against unlawful entry, in volume of ventilation attainable and in the control of drafts of air currents.

In carrying out my invention it is my pun pose to provide a simple, efficient and convenient type of window, wherein the defects, both of function and of structure incident to the ordinary window are eliminated.

A further object of my invention is the provision of novel mechanism for swingingly and slidably mounting the usual sashes in the ordinary frame and locking such sashes in a selected or desired position. By the employment of my invention, the sashes ma not only slide vertically in the usual manner, but may be swung bodily inward of the room at selected times and to a predetermined extent. For example, when it is desired to wash the window panes, the sashes may be swung inward at right angles to the frame so that the person standing within the room may readily perform the cleaning operation without the danger encountered when it is necessary to mount the ledge or window sill for such purpose. Or, when it is desired to ventilate the room the sashes may be adjusted by swinging them at any selected angle up to ninety degrees and then locked at, such selected angle, so that if desired, instead of the current of air blowing directly into the room it may be directed upward so that it enters at the to of the Window. And the mechanism I utilize for so operating and latching the sashes is exceedmgly simple, so that it may be readily applied to window frames and sashes of the usual construction.

With the above recited objects and others of a similar nature in view, my invention consists in the construction, combination, and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings: Figure 1 s a perspective view of a window embodying my invention, showing the sashes swun or tilted inward. Fig. 2 is a vertical longitudinal sectional view taken .through the window frame and sash and showing the latter locked against swinging. Fig. 3 is a rear face view of my improved metallic strip or stile which is adapted to be hingedly connected to the side of the window sash. Fig. i is a view similar to Fig. 3, but showing the window sash unlatched from the metallic stile and tilted to partly open position. Fig. 5 is a vertical longitudinal sectional view taken through a portion of a window frame and sash and showing my metallic stile applied thercto with the window sash unlatched. Fig. (3 is a view in side elevation of my improved window stile and showing the window swun inward at right angles to the stile strip. I ig. 7 is a cross sectional view taken through portions of the window sash, stile and latch, and window frame. Fig. 8 is a perspective view of the latching member carried by the stile.

In the practice of my invention I attach to each of the sash sides adjacent to the bottom thereof a specially constructed hinge which carries a steel strip or stile member, which latter is designed to slide up and down in the grooves or ways formed by the vertical strips constituting the parting bead and the sash stops of the window frame. Located in each such groove or way of the window frame is a lug or projection which is adapted to release a latching mechanism carried by the sliding steel stile and seating in a socket or bore in the sash so that such sash may be swung inward of the window to any desired angle between the vertical and ninety degrees. After the sash has been tilted or swung to a selected position, at any angle between the vertical and horizontal, it may be automatically locked by means of my improved latching mechanism so that it is positively held stationary against accidental movement or falling which would be liable to shatter the window panes.

Referring now to the accompanying drawings'in detail, the letter A designates a window frame as an entirety, at each vertical side of which is a parting head 1, and the that the plate is inset to have its sides.

I and back flush with the sides and back of the wooden stile. This plate 5 is hinged as at 7 to my improved metallic stile which is indicated as an entirety by the letters 0. As will be seen by reference to the drawings, this stile C comprises a strip 8 preferably made of sheet metal bent at one of its side edges to form a longitudinal flange 9 of a single thickness and at its opposite side edge the strip is bent forward, thence later- 1 ally inward, thence backward, thence laterally inward again to form a flange 10 having a double edge 11 and a lateral extension 11, as clearly shown in Fig. 7. This stile C is adapted to seat and slide in the guide way 3' of the window frame with the flange 9 bearing against the bottom of the guide way, while the lateral extension 11 of the flange 10 slides beneath a thin metallic strip 12 which extends longitudinally of the bottom of the adjacent guide way 3 of the window frame. The double edge 11 of the flange is designed to seat in a groove 10 cut in the adjacent side of the sash when the window is in vertical position so that the weather-tight joint is formed between the sash and stile.

Extending transversely of the back face 13 of the sliding stile or that face which confronts the bottom of the guide way in the window sash, are the brackets 14, suitably spaced apart. Slidingly arranged beneath these brackets is a metallic strip or plate 15,

which is provided throughout its upper portion with a series of spaced holes or apertures 16, while the lower portion .of said plate carries the pin 17 the shank of which extends through a vertical slot 18 formed in the body of the stile. The upper end of this pin is connected with and forms a pivot for the end 19 of the link 20, the opposite end of said link being pivotally connected at 21 to the hinge plate 5. It will thus be seen, especially by reference to Fig. 5 that "when the plate or strip 15 is unlocked, or

Twill travel downward in the slot to permit free to slide in the body 8 of the stile,as

hereinafter described, and the window is pulled downward and outward, the pin 17 the link 20 to shift'its position and permit the openin of the sash B, as shown in Figs. 4 and 6. ion the plate 15 is free to slide and the sash is pushed upward from its open to its closed position, the pin 17 will move upward in the slot and the link will be pushed inward to lie parallel with the stile 8. The upper end of this plate 15.is

i,osi,sos

bent outward 'or ofi-set as at 22 and perforated as at 23, for the attachment of one end of the sash weight cord 24, this cord running over the'usual pulleys to a weight located in the weight boxes of the frame.

In order to lock the sliding strip or plate 15 against sliding movement relative to the sliding metallic stile,-and thereby hold the window in any selected position of adjustment, 1 provide a latch comprisinga plate 25 provided with perforated ears 26 by means of which the plate is fulcrumed upon a rod 27 rigidly secured to the flanges of the sliding stile body 8. This plate isprovided at one side of this fulcrumed rod with an elongated tongue 29 carrying a laterally projecting pin 30', which is designed to project through an aperture 31 in the adjacent bracket 14 and thence through the alininghole 16 of the sliding plate 15 and through a perforation in the body 8 of the sliding stile, said pin then seating when in locking position in the alining socket or bore 34 in the adjacent side of the window frame. This locking operation of the pin 30 is best shown in Figs. 2 and 7, wherein such pin is shown in its locking position as extending through the bracket 14, the perforation 16 of the sliding strip or plate 15, the body wall 8 of the sliding stile and seated in the socket I or bore 34 in the window frame. When the latch is in locking position it will be seen that it is impossible for the strip 15 to slide in the stile and consequently the window sash cannot be swung on its hinge. To release the locking pin 30 and permit the swinging of the sash, I employ the following means:

Secured to the bottom wall of theiguide way 3 at the side of the frame is a projecting lug 35 having its top and bottom faces beveled or inclined as at 36. When it is *desired to release the latch of the window it latch from the tongue 29. As the rib end of the latch plate strikes the projection, such end will be depressed and the tongue end of the plate elevated or moved outward, of course carrying its pin 30 with it so that the locking pin will be withdrawn from the socket in the window sash, the body wall 8 of the stile and the alining aperture of the stile strip or plate 15. The plate is now free to slide and the window may be swung outward or inward as desired, in the manner hereinafter described. When it has been swung to the desired angle, it is only necessary to then'vertically slide or shift the stile and sash slightly to move the rib end of the latch 03 or away from the projection 35, when the spring 39 will again throw the tongue of the latch inward so as to project the locking pin 30 through one of the adjacent or alining apertures 16 of the plate 15 and into the socket 34.

From the above description taken in connection with the accompanying drawings, my invention will be readily apparent. If it is desired to operate the window sash in the ordinary manner, such sash is swung to vertical or closed position so that the hinge plate 5 and the link 20 lie in vertical relation to or parallel with the sliding stile C and the sash is latched in such position, to be held against swinging, as above described. When it is desired to swing the window inward at any angle from the vertical to the horizontal, or through an arc of ninety degrees, the latch is operated as heretofore mentioned, to release the locking pin and the window may then be swung inward of the room. When the desired angle of opening has been reached the sash may be locked stationary by shifting the sliding stileto carry the latch away from the tripping lug 35. 7

While I have herein shown and described one particular embodiment of my invention, I Wish it to be understood that I do not confine myself to all the precise details of construction herein set forth by way of illustration, as modification and variation may be made without departin from the spirit of the invention or excee ing the scope of the appended claims.
